About This Quest

Transform foraged plants, kitchen scraps, and minerals into rich, archival-quality inks using traditional extraction methods.

Making ink from scratch connects you to centuries of craft tradition. You're not just mixing pigments—you're extracting tannins from walnut hulls, oxidizing iron nails in vinegar, or crushing oak galls to release their chemical compounds. The process smells earthy, sometimes metallic, and the color transformations happen slowly, like watching rust form in fast-forward. Black walnut ink starts pale brown and deepens to near-black over 48 hours. Iron gall ink writes gray and turns black as it oxidizes on paper. The chemistry is forgiving but requires patience. You'll simmer plant material for an hour, strain out solids, then reduce the liquid until it's concentrated enough to write with. Gum arabic acts as a binder, keeping pigment suspended and helping it adhere to paper. Your first batch might be too thin or separate over time—that's normal. By the third attempt, you'll know the right consistency by sight and can adjust ratios instinctively. These inks work beautifully for calligraphy, watercolor washes, or pen-and-ink drawings. They're lightfast if stored properly and develop character as they age. Some medieval manuscripts still show crisp iron gall ink 800 years later. You're creating archival-quality materials from materials people throw away.

Why This Quest Matters

You'll hold ink you made from fallen walnuts and rusty nails that writes darker and more permanent than commercial bottles. The first time your iron gall ink oxidizes from gray to black on the page, you're watching the same chemical reaction medieval scribes relied on for manuscripts that still look crisp 800 years later. These aren't craft project souvenirs—they're archival-quality materials with real staying power.

What You'll Experience

Step-by-Step Guide

1

Gather and prepare raw materials

Collect black walnut hulls in autumn, oak galls from tree branches, or onion skins. For iron gall ink, submerge rusty nails in white vinegar in a glass jar and let sit for 2 weeks until the liquid turns orange-brown.

💡 Pro Tips:

  • Oak galls are the round, hard growths on oak branches—they contain the highest tannin concentration
  • The rustier the nails, the faster your iron solution develops
2

Extract pigment through simmering

For walnut ink: fill a pot halfway with crushed hulls, cover with water, and simmer 60-90 minutes until deep brown. Strain through cheesecloth, discard solids, then reduce liquid by half uncovered—it should coat a spoon when ready.

💡 Pro Tips:

  • The longer you reduce, the darker and more concentrated your ink becomes
3

Brew iron gall ink base

Crush 10-12 oak galls in a mortar and steep in 1 cup hot water for 48 hours, stirring occasionally. Strain the tea, then mix 3 parts oak gall liquid with 1 part iron-vinegar solution—watch it turn black instantly. Filter through a coffee filter to remove sediment.

4

Add binder and preservative

Dissolve 1 teaspoon gum arabic powder in 2 tablespoons warm water per cup of ink, then stir slowly into your ink base. This prevents pigment separation and helps ink grip paper. For berry-based inks, add 3-4 drops clove oil to prevent mold.

💡 Pro Tips:

  • Gum arabic can clump if added dry—always dissolve it separately first
5

Test consistency and adjust

Test with a bamboo pen or brush on paper. If ink beads up, add more gum arabic. If too thick, add distilled water drop by drop. Iron gall ink should write gray and oxidize to black within minutes.

💡 Pro Tips:

  • Test on the same paper type you plan to use—different papers absorb differently
6

Age and bottle your ink

Store in amber glass bottles and let rest 1-2 weeks for compounds to stabilize—walnut and iron gall inks improve with age. Label with date and type. Shake before each use and refrigerate for 6-12 month shelf life.
